FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60704-2-6 has been prepared by subcommittee 59D: Home
laundry appliances, of IEC technical committee 59: Performance of household electrical
appliances.
This second edition cancels and replaces the first edition published in 1994 and constitutes a
technical revision.
60704-2-6  IEC:2005 – 7 –
This bilingual version (2005-02) replaces the English version.
The text of this publication is based on the following documents:
FDIS Report on Voting
59D/224/FDIS 59D/227/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The French version of this standard has not been voted upon.
This Part 2-6 is intended to be used in conjunction with IEC 60704-1, 2nd edition 1997:
Household and similar electrical appliances – Test code for the determination of airborne
acoustical noise – Part 1: General requirements.
The relevant text of Part 1 as amended by this standard establishes the test code for tumble
dryers.
This Part 2-6 supplements or modifies the corresponding clauses in IEC 60704-1. When a
particular subclause of Part 1 is not mentioned in this part 2-6, that subclause is applicable
as far as reasonable. Where this standard states “addition”, “modification” or “replacement”,
the relevant requirements, test specifications or explanatory matter in part 1 shall be adapted
accordingly.
Subclauses or figures which are additional to those in Part 1 are numbered starting from 101.
Additional annexes are lettered AA, BB, etc.
Unless notes are in a new subclause or involve notes in Part 1, they are numbered starting
from 101, including those in a replaced clause or
